The air conditioning unit of the high speed train for through operation between Shinkansen and the converted conventional line that East Japan Railway Company will produce in the future must be installed below the floor level for low noise in the wayside area. We must integrate air conditioning unit with ventilating unit because the area below the floor level of the train is small. But the noise of this air conditioning system is large in the passenger compartments. Then, the low noise air-conditioning duct for Shinkansen was developed by using Shinkansen High-speed Test Train Type E955. The air-conditioning duct mock-up that imitated it of Shinkansen High-speed Test Train Type E955 was produced, and the evaluation and measures were examined by using it about the noise of the air-conditioning duct. As a result, we were able to reduce the noise by 3.4dB.
